[0036] As a crucial component of automotive thermal management systems, heaters primarily function to provide heat to the vehicle interior, ensuring the comfort of passengers. Currently, heaters typically consist of a housing and a base plate assembled to form a heating chamber, usually fixed together by brazing. This process is complex, inconvenient to maintain after assembly, and costly.

[0037] In view of this, the present invention provides a compressor assembly, a thermal management system, and an automobile. By using a riveting structure to fix the housing to the base plate and setting a sealing ring between the two, the assembly process of the heater is simplified, eliminating the need for complex welding equipment and processes, reducing production costs, and improving production efficiency.

[0038] To better understand the above technical solution, the following detailed explanation is provided in conjunction with the accompanying drawings.

[0039] like Figures 1 to 3 as well as Figure 9 As shown, this utility model embodiment proposes a compressor assembly, which includes:

[0040] The compressor body 200 can adopt a commonly used design structure, and the embodiments of this application are not limited thereto.

[0041] A heater 100 is located at one end of the compressor body 200 and forms an electrical control cavity with it. In other words, the heater 100 is integrated with the electrical control box of the compressor body 200, eliminating the need for a separate heater 100. The space within the original electrical control box cover is used to integrate the heater 100, effectively reducing space requirements and the overall size of the thermal management system. The heater 100 includes a housing 111 and a base plate 112, which together form a heating cavity for heating the incoming coolant. Specifically, the housing 111 and base plate 112 form a heating shell 110, with the heating cavity inside. The housing 111 and base plate 112 are fixed together by a riveting structure 130, and a sealing ring 140 is provided between them to effectively prevent moisture and impurities from entering the electrical control cavity, enhancing the sealing performance of the heater 100 and extending the service life of the equipment. Furthermore, the riveting structure 130 connects the fixed housing 111 and the base plate 112, simplifying the assembly process of the heater 100, eliminating the need for complex welding equipment and processes, reducing production costs, and improving production efficiency; and

[0042] The control board 300 is located in the electrical control cavity and is electrically connected to the compressor body 200 and the heater 100. It can be understood that the heater 100 is electrically connected to the control board 300 through electrodes or wires, and the compressor body 200 is electrically connected to the control board 300 through wires. The operation of the heater 100 and the compressor body 200 can be controlled simultaneously through a single control board 300, which is more convenient.

[0043] In this embodiment, the housing 111 is fixed to the base plate 112 using a riveting structure 130, and a sealing ring 140 is provided between them. This effectively prevents moisture or dust from the external environment from entering the electrical control cavity, thereby improving the sealing performance and service life of the heater 100. Compared to brazing, this method avoids defects such as deformation and cracks that may occur during welding, improving the safety and reliability of the product. Furthermore, it simplifies the assembly process of the heater 100, eliminating the need for complex welding equipment and processes, reducing production costs, and improving production efficiency. Simultaneously, placing the heating element 120 on the base plate 112 and / or housing 111 allows for more uniform heat conduction to the heating cavity, improving heating efficiency. Additionally, the riveting structure 130 provides uniform pressure at the connection point, reducing the probability of deformation at the connection between the base plate 112 and housing 111 due to excessive local pressure.

[0044] In one embodiment of this utility model, reference is made to Figures 4 to 6 The riveting structure 130 includes a riveting clip 131 and a riveting notch 132 that mates with the riveting clip 131. One of the housing 111 and the base plate 112 is provided with the riveting clip 131, and the other of the housing 111 and the base plate 112 is provided with the riveting notch 132. It can be understood that when the riveting clip 131 engages with the riveting notch 132, the housing 111 and the base plate 112 can be fixedly connected; when the riveting clip 131 disengages from the riveting notch 132, the housing 111 and the base plate 112 can be separated. In other words, through the engagement of the riveting clip 131 and the riveting notch 132, the housing 111 and the base plate 112 can be easily fixed together without complex welding processes, effectively reducing production costs.

[0045] Optionally, the riveting clip 131 is disposed on the housing 111, while the riveting notch 132 is disposed on the base plate 112. Of course, in other embodiments, the riveting clip 131 may also be disposed on the base plate 112, while the riveting notch 132 is disposed on the housing 111; this is not limited here. In one embodiment, the riveting clip 131 includes a first clip portion and a second clip portion that are bent and connected. The first clip portion is bent and connected to the housing 111, and the first clip portion is used to engage with the riveting notch 132. The second clip portion abuts against the side of the base plate 112 facing away from the housing 111. Thus, the base plate 112 can be clamped by the cooperation of the second clip portion with the housing 111, thereby fixing the housing 111 and the base plate 112.

[0046] In one embodiment of this utility model, one of the housing 111 and the base plate 112 is integrally formed with the riveting head 131. This improves structural strength, increases the service life of the heater 100, and reduces operating costs.

[0047] In one embodiment of this utility model, reference is made to Figure 3 At least one of the housing 111 and the base plate 112 is provided with a mounting groove 170, and the sealing ring 140 is installed in the mounting groove 170. It is understood that the mounting groove 170 facilitates the installation of the sealing ring 140 and also secures it, preventing displacement and ensuring proper sealing performance. In this embodiment, the sealing ring 140 protrudes from the mounting groove 170. After the base plate 112 and the housing 111 are connected by a riveting structure, the base plate 112 and the housing 111 apply pressure to the sealing ring 140, causing it to deform and forming a closed cavity inside the sealing ring 140.

[0048] In one embodiment of this utility model, reference is made to Figure 3 and Figure 4 The heater 100 also includes a liquid inlet pipe 161. The housing 111 is provided with a liquid inlet, and the liquid inlet pipe 161 is connected to the liquid inlet. The liquid inlet pipe 161 can deliver the coolant with a lower temperature in the thermal management system to the heating chamber. The liquid inlet direction of the liquid inlet pipe 161 is parallel or perpendicular to the axis of the compressor body 200, which can be flexibly adjusted according to the specific vehicle layout and space constraints, thus improving adaptability.

[0049] And / or, the heater 100 also includes a coolant outlet pipe 162. The base plate 112 is provided with a coolant outlet, and the coolant outlet pipe 162 is connected to the coolant outlet for discharging the heated coolant from the heating chamber back into the thermal management system for use in vehicle interior heating or battery heating, etc. The discharge direction of the coolant outlet pipe 162 is parallel or perpendicular to the axis of the compressor body 200, which can be optimized according to the overall vehicle layout requirements to ensure smooth coolant flow.

[0050] In one embodiment of this utility model, reference is made to Figure 4 and Figure 8 The heater 100 also includes a turbulence structure 150 disposed inside the heating chamber. The turbulence structure 150 has multiple spaced-apart turbulence sections, with flow gaps formed between the multiple turbulence sections. This lengthens the flow path of the coolant inside the heating chamber, thus increasing the heating time and effectively improving heat transfer efficiency for better cooling. With the same heat transfer efficiency, the overall size of the heater 100 in this embodiment can be made smaller, further improving the structural compactness.

[0051] In one embodiment of this utility model, the turbulence structure 150 is a turbulence protrusion disposed on the inner surface of the heating cavity; or, the turbulence part is a turbulence fin separately disposed from the heating cavity. It is understood that in one embodiment, the turbulence structure 150 is a turbulence protrusion, which is integrally disposed with the housing 111 or the base plate 112, thus reducing the number of parts and lowering assembly difficulty and production costs. In another embodiment, the turbulence structure 150 is a turbulence fin, which is assembled in the heating cavity, thus facilitating disassembly and maintenance.

[0052] In one embodiment of this utility model, a base plate 112 is disposed between the housing 111 and the control plate 300. The base plate 112 has a mounting surface 113 facing the control plate 300, and a heating element 120 is disposed on the mounting surface 113. This results in a shorter distance between the heating element 120 and the control plate 300, facilitating electrical connection between them. A heat insulation member 400 is provided between the base plate 112 and the control plate 300. Figure 2 It is understandable that the heat insulation component 400 can isolate the heat generated by the heating element 120 during operation, reduce the heat transferred to the control board 300, prevent the temperature of the control board 300 from rising too quickly and affecting normal operation, thereby reducing the adverse effects of the high temperature of the heating element 120 on the control board 300.

[0053] In one embodiment of this utility model, the heating element 120 is a heating film. It is understood that compared to traditional heating components, the heating film is lighter, reducing the weight of the heater 100 and thus the overall weight of the vehicle, improving the driving range of the electric vehicle. Simultaneously, due to the efficient heating characteristics of the heating film, the required heating effect can be achieved with lower energy consumption, helping to reduce the overall energy consumption of the electric vehicle. It is understood that the heating film generates heat when energized, and the heat is conducted to the heating shell 110, thereby heating the coolant. Optionally, the heating film is sintered and attached to the outer surface of the base plate 112, i.e., the surface facing the control board 300. This securely attaches the heating film to the base plate 112, reducing the complex fixing structure and connectors found in traditional heaters 100, simplifying the overall structure. The sintering process improves the weather resistance and reliability of the connection between the heating film and the base plate 112, better adapting to various harsh environments. The heating film is provided with a connecting electrode 180, as shown in the figure. Figure 7 The connecting electrode 180 is electrically connected to the heating film and the control board 300. The heat insulation component 400 is provided with a clearance 410, as shown in the reference. Figure 2 The connecting electrode 180 passes through the clearance 410, thus allowing the connecting electrode 180 to pass through the heat insulation component 400 from the clearance 410, thereby achieving electrical connection between the heating film and the control board 300. Specifically, the heat insulation component 400 can be a plate-like structure made of glass fiber, asbestos, rock wool, etc.
